Opis:
The adsorption of Eurozol Navy Blue (ENB) reactive dye was examined using banana peel and sugarcane bagasse powders. Several parameters such as pH, contact time, agitation speed, temperature, initial dye concentration, and adsorbent dosage were considered and their impact on dye adsorption efficiency was evaluated. The removal percentages of ENB dye due to adsorption on banana peel and sugarcane bagasse were 72% and 70%, respectively. Simultaneous dosing of both biosorbents resulted in 68% dye removal. The Langmuir isotherm model was found to fit the adsorption of ENB dye on banana peel and sugarcane bagasse powders. The corresponding maximum adsorption capacities were equal to 24.09, 32.46, and 27.54 mg/g for banana peel powder, sugarcane bagasse powder, and the mixture of adsorbents, respectively.

Opis:
Drought is regarded as one of the environmental constraints threatening agriculture worldwide. Melatonin is a pleiotropic molecule prevalent in plants capable of promoting plant endogenous resilience to many environmental challenges including drought. Banana is an important staple food consumed in developing countries especially in Africa. In this research, we studied the role of melatonin in the growth of bananas subjected to drought under the Egyptian semi-arid conditions. To achieve this objective, a field experiment on banana (Musa spp., cv. Williams) mother plants and first ratoon was conducted on a private farm for two seasons - 2019 and 2020. Three irrigation treatments, 100, 90 and 80% irrigation water requirements (IWR) were used in conjunction with four concentrations of melatonin as a foliar spray (0 μmol, 40 μmol, 60 μmol, and 80 μmol) to determine the effect of both treatments on banana plant performance under drought. The results showed that there was a substantial difference between treatments, with the foliar application of melatonin at 80 μmol concentration improving most of the yield attributes, relative water content, total chlorophyll and proline with water deficit. However, the foliar application of the molecule lowered the biochemical characteristics mostly at 80% IWR under the Egyptian semi-arid conditions. Overall, there was a concentration-dependent response with regards to IWR for the two seasons 2019 and 2020.

Opis:
The effects of climate change on agriculture may have strong impacts on the world’s food economy and are likely to threaten both the welfare of the world’s population and the economic development of the global society. Hence, the impacts of changes in important climate variables like temperature, rainfall and relative humidity on the production of a major food commodity called banana is investigated using the data obtained within 1998-2012 from Ondo State, Nigeria. The results suggest that excessive rainfall and extremely high temperature can reduce banana productivity while the production is also small when both rainfall and temperature are very low with poor humidity. On the average, the findings show that a mean temperature of about 26 °C and average rainfall of around 1891mm with relative humidity of approximately 77% will lead to good annual banana production above 61,000 tons in Ondo State. Since these climate variables will fluctuate under a future climate change condition, the coping strategies recommended for farmers in the area and in similar places might include planting of drought- and disease resistant banana types, monitoring of weather conditions, use of irrigation and chemicals. Improved storage facilities are also important while transportation of banana should be done under controlled conditions to avoid spoiling the quality.

Opis:
The study’s purpose was to reduce the oxidative stress, seasonal physiological changes of paspalum vaginatum and ameliorate soil properties through the addition of banana waste biochar and compost. Different rates of organic amendments were incorporated into sandy loam soil to investigate their impact on paspalum physiological, biochemical, and development in pot and field settings over three seasons (winter, spring and summer). Under the conditions of these two places, paspalum leaves gas exchange characteristics, stomatal traits, anatomy traits, relative water content, proline, antioxidant enzyme activities, and paspalum pigments were determined. For the irrigation system, two rates were chosen: 20% and 60% of the water holding capacity of the control plot WHC. In this study, two advanced statistical analyses were conducted. A factor analysis of mixed data (FAMD) was performed for the analysis of the effect of our charcoal on soil data. Meanwhile, the impact of banana waste biochar on biological activities was investigated using multiple factorial analysis (MFA). The use of biochar and compost blends boosted the cation exchange capacity (CEC) of treated soils, according to our findings. Furthermore, the use of banana waste biochar improved biological basis in the summer season compared with previous seasons. Different antioxidant capacities in seashore paspalum were boosted in the improved soils compared to the untreated ones.

Opis:
In this article, the potential use of banana bunch waste (BBW) as a source of bioenergy through hydrothermal carbonization (HTC) was investigated. BBW, a byproduct of banana production, is difficult to use as a fuel due to its low density and carbon ratio. However, its high lignocellulose content indicates its potential as a bioenergy source. To determine the optimal HTC conditions, an experiment was conducted using temperature, water to feedstock ratio, and processing time, with the RSM Box-Behnken method used to produce 15 trial formulations. Energy value and mass yield data were collected to determine the optimal values for both. The main parameter affecting energy yield was found to be the water to feedstock ratio, and the optimal conditions were determined to be a temperature of 180 °C, a water to feedstock ratio of 1.5:1, and a processing time of 15 minutes. The highest energy yield of 99.7% was observed under these conditions, while the lowest mass yield of 25.30% was observed at a temperature of 200°C with a water ratio of 2 and a time of 15 minutes. The heating value of the HTC solid product ranges from 17–27 MJ/kg, which is comparable to low-grade sub-bituminous coal, indicating potential for co-firing with coal and other hydrothermal products as a fuel.

Opis:
The heavy metals pollutants resulting from industrial wastewater are a major environmental problem due to their toxicity and non-biodegradability. Their removal became a trending environmental subject. The preparation of low-cost and eco-friendly adsorbents for industrial wastewater treatment has been widely investigated. Furthermore, the use of polymeric material for this purpose is highly increasing. In this study, banana stem agro-waste was valorized by preparing and characterizing its derived activated carbon used as a filler to improve the adsorption performance of polyurethane foams. The loaded polyurethane was synthesized in the shape of pellets, characterized by SEM, and tested in removing Pb2+ and Cu2+ from aqueous solutions. The effects of activated carbon filler concentration, number of filtering passes, and pH were examined. The loaded polyurethane demonstrated a good adsorption capacity that was enormously improved compared to the unloaded polymer. 77% Pb2+ and 40% Cu2+ removal were reached after one filtering pass only. The optimum pH was determined to be 4. After the 10th pass, and at any pH, almost 100% of the studied metals were eliminated. Rapid and straightforward selectivity and seawater deionization tests were carried out and confirmed the capacity performance of the prepared pellets in removing different aqueous ions.

Sweet Hereafter
Opis:
The natsukashisa (nostalgia) is a common key to interpretation of novels written by the Japanese author Yoshimoto Banana. Considered as the desire for a replay of life, nostalgia is evaluated as a solution for the sensation of emptiness and solitude attributed to modern life; a gap that can be bridged by memory, recollection and flash-backs of the protagonists in Yoshimoto’s novels. As a representation for something gone, the objects of this nostalgic feeling assume different forms in Yoshimoto’s works: a faraway house, a lost person, a feeling perceived and then missed; dreams, hallucinations, images and paintings: everything is transformed by the author in a vehicle to allow the reader to sympathize with the protagonists and share the same nostalgic feeling. Author’s attempt is to encourage the young readers to keep on seeking the lost self in the past in order to not betray one’s identity. This is the main topic one can also recognise in her novel called Sweet Hereafter, a publication in which nostalgia for a self lost in a car accident is compared to the one felt by the hisaisha of Tōhoku region who lost everything after the earthquake and tsunami that hit Japan on 11th March 2011. Here Yoshimoto suggests natsukashisa as the possible way to overcome the traumatic experience of witnessing Japanese Daishinsai. This brief investigation proposes a literary case study that highlights the relation between trauma and memory, with a particular focus on nostalgia considered as a positive means for overcoming traumatic experience.

Opis:
The current study aimed to evaluate the effect of banana waste biochar on the physiological traits and growth of Paspalum vaginatum under three water treatments (100%, 80%, and 60% of the water holding capacity (WHC) of the soil). A plastic pot experiment was done for the germination of paspalum vaginatum. The treatments were the addition of compost, banana waste biochar, or banana waste biochar and compost combination to the soil. We used multiple factor analysis (MFA) to reveal the relationship between the effect of banana waste biochar and the three water regimes on physiological data. The findings revealed that banana waste biochar had an important impacts on all traits under various water supply conditions. The photon yield of PSII of control treatment at three water regimes had the lowest response compared to amended treatments. Changes were observed in chlorophyll pigment among different treatments.

Opis:
The purpose of this study was to use statistical techniques to characterise bio-composites made from sisal fibres and bio-resin from raw banana peel. The fibres were treated with sodium hydroxide, combined with a bio-resin made from banana peel, and then a bio-composite material was developed. The effect of the fibre volume fraction, glycerine and bio-resin mass on the bio-composite’s tensile and compressive properties was investigated using universal rotatable design and multiple regression. The paired T-test conducted exhibited a significant improvement in the mechanical properties of the treated fibres. Sisal bio-composite showed a tensile strength of 5.2 MPa with an adjusted R2 value of 0.91, Young’s modulus of 11.99 MPa (adjusted R2 of 0.92), percentage elongation of 1.77% (adjusted R2 of 0.95), and compressive strength of 2.94 MPa (adjusted R2 of 0.90). The bio-composite could becompared to a commercial composite and solid wood boards, and hence it is an alternative to non-renewable, non-biodegradable petroleum and solid wood products for partition, ceiling and notice board applications.
Celem pracy było wykorzystanie technik statystycznych do charakteryzowania biokompozytów wykonanych z włókien sizalowych i biożywicy z surowej skórki banana. Włókna potraktowano wodorotlenkiem sodu, w połączeniu z biożywicą ze skórki banana, a następnie opracowano materiał bio-kompozytowy. Zbadano wpływ frakcji objętościowej włókna, gliceryny i masy biożywicy na właściwości rozciągające i ściskające biokompozytów, wykorzystując uniwersalną konstrukcję obrotową i wielokrotną regresję. Sparowany test T-test wykazał znaczną poprawę właściwości mechanicznych obrabianych włókien. Bio-kompozyt wykazywał wytrzymałość na rozciąganie równy 5,2 MPa przy skorygowanej wartości R2 wynoszącej 0,91, module Younga 11,99 MPa (skorygowany R2 równy 0,92), procentowym wydłużeniu 1,77% (skorygowany R2 równy 0,95) i wytrzymałości na ściskanie wynoszącej 2,94 MPa (skorygowany R2 równy 0,90). Biokompozyt można porównać do komercyjnego kompozytu i litego drewna, a zatem może być alternatywą dla nieodnawialnych, niebiodegradowalnych produktów z ropy naftowej i litego drewna do zastosowań w ścianach działowych, sufitach i tablicach ogłoszeń.

Opis:
Flame retardancy was imparted in cellulosic cotton textile using banana pseudostem sap (BPS), an eco-friendly natural product. The extracted sap was made alkaline and applied in pre-mordanted bleached and mercerized cotton fabrics. Flame retardant properties of both the control and the treated fabrics were analysed in terms of limiting oxygen index (LOI), horizontal and vertical flammability. Fabrics treated with the non-diluted BPS were found to have good flame retardant property with LOI of 30 compared to the control fabric with LOI of 18, i.e., an increase of 1.6 times. In the vertical flammability test, the BPS treated fabric showed flame for a few seconds and then, got extinguished. In the horizontal flammability test, the treated fabric showed no flame, but was burning only with an afterglow with a propagation rate of 7.5 mm/min, which was almost 10 times lower than that noted with the control fabric. The thermal degradation and the pyrolysis of the fabric samples were studied using a thermogravimetric analysis (TGA), and the chemical composition by FTIR, SEM and EDX, besides the pure BPS being characterized by EDX and mass spectroscopy. The fabric after the treatment was found to produce stable natural khaki colour, and there was no significant degradation in mechanical strengths. Based on the results, the mechanism of imparting flame retardancy to cellulosic textile and the formation of natural colour on it using the proposed BPS treatment have been postulated.

Opis:
Cavendish banana is a climacteric fruit with a fast response to ethylene and a very high respiration rate during storage. Previous studies revealed that these characteristics shortened the green-life and fastened fruit damage, affecting the economic value. Therefore, this study aims to examine the effects of fruit maturity levels, coatings, and storage temperatures on the qualities and green-life of Cavendish banana. The result showed that the level of fruit maturity significantly increased the green-life duration, as well as maintained firmness, diameter loss, acidity, and starch content, but it had no effect on weight loss, oBrix, and glucose. Meanwhile, low temperature was able to delay senescence, promote starch degradation, as well as detain firmness and diameter loss. The results also showed that the combined application of maturity levels + temperatures affected all parameters, while maturities + coatings as well as coatings + storage had effects on firmness, acidity, and starch content. The 1% chitosan coating coverage was analyzed with a Scanning Electron Microscope (SEM), which showed fully covered surface of M1 finger rind tip and some crack points on finger rind base. Furthermore, there was full coverage on M2, and some crack points on M3.

The development of nanoadsorbents for remediation of polluted water in order to obtain clean and healthy water quality has been carried out, namely the incorporation of chitosan, magnetic, and activated carbon materials. The activated carbon used is the result of the synthesis of banana peel waste nanocrystals, while the magnetic is Fe3O4. The method used in this study is an experimental method with coprecipitation through several stages, namely (1) magnetic synthesis of Fe3O4 by thecoprecipitation method, (2) preparation of chitosan solution, (3) synthesis of activated carbon nanocrystals from banana peel waste by the milling process, (4) merger of the three materials, and (5) characterization with SEM/EDX, XRD, FTIR, BET, PSA, TGA, and AAS to test the performance of the material against polluted water. The study found that 210 minutes was the optimal time for the heavy metal ions Fe, Mn, Zn, and Pb to adsorption.The best sample was sample S4 with a ratio of 1:2:2 with adsorption for Zn 92.43%, Fe 95.44%, Mn 89.54%, and Pb 84.38%. For the heavy metal ions: Mn 5624 mg/g, Fe 5849.4 mg/g, Zn 4894.22 mg/g, and Pb 468.2 mg/g, the Langmuir model was used. The adsorption kinetics showed that the reaction order for Pb, Mn, Zn, and Fe ions varied with pseudo-first order and pseudo-second order. Carboxymethyl cellulose nanoadsorbents are effective in remediating the water contaminated with heavy metals, such as Pb, Mn, Zn, and Fe, meeting the environmental health quality standards for water media for sanitation hygiene purposes.

Opis:
The opportunity of utilizing activated carbon prepared from banana peels (BPAC) as a permeable reactive barrier (PRB) to eliminate copper Cu$\text{}^{+2}$ from the contaminated ground water has been explored. The activated carbon was prepared from banana peels by chemical activation utilizing a drenching agent, for example, a phosphoric acid (H$\text{}_{3}$PO$\text{}_{4}$). The Influence of different factors including initial copper amount, contacting duration, agitation speed, initial pH of the solution and sorbent dosage was studied in batch experiments. The optimum magnitudes for these factors that resulted in the highest copper removing efficacy (96%) were 40 minutes, 6, 250 rpm, 50 mg/l, and 1 mg/100 ml, respectively. The isotherm models of Freundlich and Langmuir have been utilized to analyze the sorption data for Cu$\text{}^{+2}$ ions acquired via batch studies. The Langmuir model has been utilized to explain the sorption of Cu$\text{}^{+2}$ onto BPAC, according to the findings. The partial differential formulas that describe copper transport in one–dimensional (1D) under equilibrium conditions have been solved utilizing COMSOL Multiphysics 3.5a software based on the finite element technique. The PRB has a significant function in preventing the copper plume from moving, according to the expected findings (COMSOL solution) and experimental findings. Finally, the excellent agreement between anticipated (theoretical) and actual findings, with an RMSE of less comparison with 0.1%, demonstrated that these techniques are useful and efficient instruments for describing copper transport processes.

Opis:
Unlike four decades ago, today-safe in our privilege-we, Poles, are allowed to protest. Irrespective of the brutality of the riot police and despite evident instances of the abuse of justice, the consequences of participation in peaceful demonstrations are incomparably less tragic than it was the case in the early 1980s. And yet it would be impossible not to notice the profundity of the yawning abyss between the palpable reality of desperate acts of self-immolation and the safety of Facebook-based philippics, between the individual tragedies of dying hunger strikers and the “intimate revolts” of those who-having much too much to lose-speak out against the collapse of essential values in the serene sanctuary of their homes. The tragedy of the irony of the self-fashioned righteousness seems to match the irony of the real tragedies: the (post)modern hamartia seems to be well illustrated by the difference between two musical interpretations of Ernest Bryll’s disconcerting protest song “I Still Carry My Poems,” first arranged and performed in the 1980s by Tomek Opoka, and then reinterpreted and reinvented in 2009 by the Banana Boat, whose version was included in an album created by Piotr Bakal in memory of the blind bard. The present reflections, therefore, address the phenomenon of the ironic protest, in which self-made heroes thrive, and tragic protesters become invisible, their humanity transformed into an icon.

Opis:
This study was executed to investigate the potential of agar-agar, a nontoxic and non-degradable gelling agent, as a promising coating agent to improve and protect banana fruit against fungal postharvest diseases i.e., crown, finger, neck and flower end rots which are caused by fungal isolates of Colletotrichum musae and Fusarium moniliforme. Coated-banana fruit samples with different concentrations of agar-agar suspension particularly at 2.0 g · l−1 exhibited a significant reduction in incidence and severity of postharvest diseases compared to untreated fruit. Banana fruits dipped in agar suspension at 2.0 g · l−1 for 5, 10 and 15 min showed significant reduction in disease incidence and severity. Moreover, application of agar suspension as a coating agent at 2.0 g · l−1 significantly decreased weight loss (%), firmness loss (%), and soluble solid concentration of banana fruit for 15 days at 25 ± 2°C. Scanning electron microscopy observation confirmed that the fruit coated with agar colloid at 2.0 g · l−1 had significantly fewer cracks and showed smoother surfaces than untreated fruit. This explains the quality improvement in agar-coated fruit compared to uncoated fruit. Overall, agar colloid, a safe coating agent, could be used to protect banana fruit against postharvest rot diseases and extend fruit storage life during ripening and storage.
